This invention relates to improvements in safety razors.

It is a primary object of the invention to provide a ra`zor framerendering more conf' venient the introduction or removal of the blade toor from the frame.

Itis a further object to avoid all possible i contact. of the` fingersof the user with the kof ,an improved blade for facilitating itsadaptation to the present invention without:

blade-holding parts wherever possible.

A stillfurther object is in the provision sacrificing any lfeature ofholding the blade i the drawings in which:

stationarywhen in use.

These and other objects will appear more fjully when considered inconnection with Fig. 1 is a longitudinal sectional view showing one formof my invention. f

Fig. 2 is a similar view showing the parts movedto blade-removingposition,

' Fig. 3 is a view similar to Fig. 1 showing a slight modification of myinvention.

' Fig. 4 is a sectional view showing the parts moved to blade-removingposition.

Figg is a detail view showing a modified form of blade and supportinelements.

Fig. 6 is a detail view o the blade employed herein.

The abovefeatures are provided in `the present construction by forming ashank 8 of hollow internal section andformed with.

by making-the same integral or swaging or' flanging the parts togetheras shown. The

` `outer face of the plate 12 is provided with vprojecting studs 13 forreceiving the apertured blade 11 and the apertured plate referred tobelow. y

The outer plate 14 is pivotally connected to the stem 10 as by means ofthe pivot 15. It is preferred to maintain the plate 14 in eithertransverse or longitudinal relation with respect to the stem 10 soas tomaintain these parts in any set position. This may be accomplished byproviding a slid- -able plunger 15 for engagement with the innersquared. shoulder 16 formed on the projectingl pivot-forming portion ofthey plate 14. Plunger 15 and compression spring 20.may be mounted in asuitable recess within the interior of the stem 10.

In the preferred form of the invention the outer surface of the guard 12and inner surface of the plate 14 are curved transversely to flex theblade 11 into its shaving position.

The stem 10 is lformed withthe screwthreaded portion 22 for receiving anengagement collar A24 vheld in place on the stem as by means of thesecuring nuts shown. The screw-threaded` portion 22 projects outwardlybeyond the collar 24 for engagement with the inner screw-threadedportionu and engageable by the collar 24 when the operating member 26 ismoved outwardly. The outer face of the guard 12 and the plate 14 are.formed with co-acting studs and apertures for supportingthe blade dur'v`ing the use of the samerthe studs serving to place the blade during theassembly of the same onto therazor. I

If preferred the collar 24 may be made of resilient material tofacilitate the ipping between the'cylindrical portion o the operatingmember and this collar durin the operation of the parts as describebelow.

when iefie desired @introduce e blade vonto the razor frame disclosed,the operating f member 26 is unscrewed from the threaded portion 22 of-the stem 10. The operating member isv then moved downwardly to thedotted line positionshown in Fig. 1 until the tapered portion 28-engages and grips the collar 24.. The operatlng member is then thrustupwardly into the` razor thus pushing the plate 14 outwardly away fromthe guard 12. Atthe same time the operating member 26 may be turned toplace the plate 14 transverse to the guard 12 as shown in Fig. 2.l Theplate 14 may then be turnedyintoits vertical position and the bladepassed over the same into position on the securing studs, after whichthe plate will be tilted into substantially the plane of the guard 12and lwill be turned to, permit the` apertures thereonto engage.

over the securing studs. The operating member may then-be screwed ontothe stem 10 and the razor is ready for use. v

In the modified form of my invention shown in Figs. 3, and 4 theconstruction and operation is substantially 'the same except that anadditional yspring member of rust-proof steel is attachedto the stem 10and is always engaged with the inner surface ofthe cylindrical vportionof the operating member 26a. With this form of the invention a bettercontrol for the outer plate 14a is obtained since the constantfrictional engagement between the member carried on the'stem 10 and theinner surface of the operating member 26a permits lthe operating memberto be unscrewed from "the stem 10 and moved outwardly. after whichpresguard should be accurately positioned tot .hold the samel in shavingposition.

sure upon the operating member moves the stem 10 and plate 14acorrespondingly.

If desired the spring-pressed-member may be formedby separating a thinpiece of the metal Ifrom the stem 10 instead of forming the frictionspring as' a separate element.

In Fig. 5 I have shown` aslightly diersurfaces for receiving a rigidbalance blade 11b. The parts illustrated in Fig. 5 are illustrated toshow that either the irst, or second form of my invention describedabove` is adaptable for use with a rigid blade.

In Fig. 6 I have shown a preferred form of blade for use in this razor.As stated above it is intended 4to pass the blade over thelongitudinally .extended plate and onto the anchoring lugs of the guard.It is desirable however to remove as small a portion of the -metal ofthe blade'as possible to .accomplish this function;l Furthermore the,blade when introduced onto the' studs of the These features are providedfor in the blade shown in Fig. 6 wherein the blade 11 1s formed withacentral slotted 'portion 32 having elongated arcuate side portions ofsubstantially the same contour as the transverse curvature of the outerface of the plate 14. These curves are preferably the same'on both sidesof the median line of the' blade so that the blade may be 'turned -witheither side of blade positioned adjacent the down-turned plate. The slot3 2 vtosaid stem and shank. r

Istantially ninety degrees each the same and terminates in circularslots 34 of slightly less than a complete circle- It A is preferredthatuthe periphery-of the openings 34 occupy'substantially more thansemicircles in order to 'securely anchor the blade with respect to the.guard and both securing studs on the same. v Je v Having now describedmy linventlon., I claim: V l i 1.
